Summary: Coyote communication occurs mostly via eye contact, facial expressions and body language and it can be very subtle. Coyotes are not forever vocal as humans are; they tend to be on the quiet side — except when they aren’t! Here I explain their voice communications, based on my own daily dedicated observations over the past 11 years, and then I give about 20 examples, chosen from about a thousand that I’ve recorded.

In the video, after sirens sounded, first there was a howling session, then some greeting and hierarchy interactions which included nose touches, dominance displays, body contact, submissive displays and confirmations. And then this! Pestering? Teasing? Demand for attention? Challenging? Provoking??? Or maybe he’s just simply not doing what she wants him to do?

The two coyotes *of interest* are an older mated pair with a family of yearlings and pups. I’ve seen an established routine of antagonism between the two whereby the female snarls, and grunts at *him* and he simply ignores her or turns away after, often, responding with a snarly grimace. She continues to groom him sometimes, but also they tend to walk right past each other as ships in the night without acknowledging the other’s presence. The male is a rather easy going fellow. The female appears to be older than he is — she’s the one doing the prodding. The territory is one in which the male was born and the female then joined him and they’ve been together ever since.

I know another mated pair where there seems to be more antagonism as the pair has aged. The male is much older than the female: he is 8.5 years old and she is 4.5 years old. They’ve raised two pups over the course of three seasons who they keep well hidden. Their relationship began with the male being very solicitous and careful. More recently, and maybe it’s because he’s quite old and in pain, I’ve seen him become grouchy on occasions, even throwing *her* to the ground when she pinches him by mistake while grooming him. She ducks or falls on her back, and then, when his anger is over, she continues grooming him because he apparently demands it by standing next to her: her job is a chore now though it didn’t used to appear that way.

This video is a very short (20 seconds) clip of a youngster coyote, a little over four months old, responding to the howls of his family after a siren had sounded. He is on one side of the park alone, independently and very self-sufficiently, exploring and hunting on his own. It’s late dusk and there’s almost no light, but the camera was able to focus on this. Notice that the youngster is listening intently for the rest of the family which is far in the distance, in back of where I’ve standing to video. When he thinks he knows where they are, he takes off in their direction, running.

Interestingly, as he approached them, he veered off and went the other way, never meeting up with them. The howling had stopped by the time he reached them. Might he have decided to avoid what was going on between them? There were four other coyotes who were at the site, including Mom, Dad and two yearling siblings born last year.

I say this because it’s at this point that I and another onlooker heard strong deep warning growls. We heard them again, and then a third time. It’s not often that we hear coyotes actually growl like this because it seems to be limited to use within the coyote world between themselves, apparently to express anger or discipline. Unfortunately my recorder did not pick up the low frequency sounds.

I strained to see what was going on but could only make out that one coyote had pinned another one down and was growling at it. By focusing my camera on the light in the background, I was able to get these two photos below. Once home, where I could actually see the image, I could tell clearly that Mom was standing over her yearling daughter, exercising her dominance. Dispersion time is coming soon for that young female. Punches, nips and dominance displays as this one will increase in order to drive the youngsters off. This is an important part of the coyote’s life cycle: it keeps the population down in claimed territories.

Interestingly, Dad still grooms this female for long stretches of time and very affectionately, reconfirming his bonds and affection for her. In the families I’ve observed, it seems to be the Moms that drive out the females (who I suppose could become competitive with them), and the Dads, or sometimes male siblings, who drive the youngster males out.

This video shows one of two coyotes who are yipping back and forth together. You can clearly see how she uses her mouth muscles — pulling them back or pushing them forward — to achieve the yipping or yodeling sounds. Humans do this too, but we have the additional use of our tongues which allows us to produce speech.

Many people mistake these high-pitched coyote yips for pup sounds when they can’t see who is making them, but as you can see here, it is adults who are making the sounds! These two coyotes began this yipping session after ambulance sirens were heard — which is a common response by coyotes.

I asked a very good friend if he thought this video might be too long for viewers. This is what he said:

“It is wonderful, & beautiful — particularly the sound, and the length, which both are perfect — nature is slow… those digitalkids & iphonephreaks who believe they live in a soundbyte world, don’t — there are entire worlds out there, surrounding them and containing them and of which they are a tiny miniscule and unimportant part, which move far more slowly — Nature is one of those, Geology moves far more slowly even than that — Astral events, the stars, move both far more slowly and sometimes a whole lot faster, than they do — let the slowness here, decorated so wonderfully by that chirping-birds & airplane soundtrack, remind them of their own relativity in all of that”.

This video is long, at 5:51 minutes. The most interesting parts are the tiptoeing at 1:10, the series of pounces where she caves in the underground tunnels of her prey at 1:44, and then the furious digging and moving of ground cover at 2:17. She exposes her prey by this digging and grabs it at 3:28 and then eats it. A young female shows how adept she is at her hunting routine:

Here is a breakdown of what is occurring:

To begin with, patiently, she stands there, super alert, watching and listening, triangulating her ears from side to side, and nodding her head back and forth to exactly and precisely locate her prey by sound.

At 1:10 she tiptoes, ever so carefully so that her prey may not hear her — a little bit closer

Soon thereafter, at 1:44 she tenses, getting ready to leap, backs up a little bit and then springs up and down into several pounces, landing hard on her forepaws with a series of “punches” meant to knock in her prey’s intricate tunneling system underground. This prevents the gopher from escaping through that tunnel network. This lasts until 2:05.

At 2:17 she begins furiously digging and digging, both deep into the ground to break through into the tunnels, and on the surface to move the ground-cover out of the way, all the while continually keeping a wary eye on her surroundings, including me and folks walking in back of me.

At 3:28 she catches her prey, disables it, and tosses it to the ground. Then, by looking around, she assesses how safe it is to eat right it then and there. She decides it’s not so safe, so she runs off with it.

At 3:36 until the end of the video, she eats her prey, tearing into several more manageable eating portions and chewing these down to swallowable sizes — it takes a while, and then she calmly walks off. Note that there is no waste — she eats every bit of her prey: entrails, muscles, fur and bones.

This posting is a slightly revised and expanded version, with photos, of what was originally written for, and posted on, Bernalwood.com on May 27th.

coyote at dawn

We have coyotes in most of our parks here in San Francisco, and most folks I’ve spoken with are thrilled about it! Enjoy it and respect its wildness! At the same time, there are some people, especially pet owners, who are not so thrilled. Here is some information I’ve put together about coyotes, much of it based on my own observations, as a response to concerns and comments which have appeared in some of the social media recently. This is information that applies to urban coyotes everywhere, not just here in SF.

COYOTES ARE TERRITORIAL AND LIVE IN FAMILIES

coyotes in our parks

Most parks in San Francisco have one stable resident family, or a loner. Coyotes are not “pack” animals of unrelated individuals. Families “claim” territories which they “own” from which they exclude other coyotes — this is what keeps the population density down. They trek through the neighborhoods every night, during the early morning or early evening hours — and, more rarely, during the brightest hours of the day — marking their territories to keep other coyotes out and looking for hunting opportunities. Studies show that in urban areas, there is generally about one coyote per square mile — a family of 4 would require about 4 square miles. You will always be seeing the same individual coyotes in any particular area.

Although we have parks with loner coyotes, most parks have mated pairs with families. Coyotes mate for life, and both parents raise the young. Coyotes mate in January or February and produce young in April — births occur only once a year.

The number of family members fluctuates up and down continually over time. In one park, it went something like this: 2-5-3-4-2. The fluctuation is due to new pups, and then to their dispersal or deaths. There is only about a 30% survival rate of pups during their first year — disease and nutritional issues take their toll.

When it’s time for youngsters to “disperse”, the parents will drive them out, or they may just pick-up-and-go. This usually occurs between one and two, and sometimes three years of age, and it occurs throughout the year — there is no “dispersal season”. However, the breeding adult pair will remain in the same territory over many years. Interestingly, wolves will actually kill their own kin in order to preserve their own statuses and territorial rights. I’ve not seen this in coyotes, but I have seen the altercations that drive coyotes out of their birth territories.

Cars are urban coyotes’ chief cause of death — please drive carefully! They often trek on our traffic grid — it’s often the “path of least resistance”. A few days ago, in our Diamond Heights neighborhood, a car swerved right into someone’s house to avoid hitting a coyote during the early morning hours.

MORE ASSERTIVE OR INSISTENT BEHAVIOR

As the individuals in a family mature, some of them may go through phases of what might be called more “assertive”or “insistent” behavior, such as: following or running in the direction of a dog. During pupping season, the assertiveness is strongest, with coyotes even approaching and possibly even nipping at a dog’s haunches. These are coyote “messaging” behaviors: coyotes want dogs to move on and to know the territory is taken. These behaviors don’t “define” a coyote, and they don’t last. Think of these as phases in a teenager’s life, or in a parent’s life — there’s an ebb and flow to behaviors for each coyote, often based on what is going on within the coyote’s individual family: Are there new pups? Is there increased sibling rivalry? Are parents having issues with the offspring, or trying to get one to disperse? I’ve seen no evidence to indicate that such behaviors build up towards more aggressiveness. Many of the more apparently “assertive” behaviors, both in juveniles and adults, are based solely on circumstances and happenstance encounters, so keep your distance.

SIGHTINGS

trekking through the neighborhood

A substantial increase in “sightings” doesn’t necessarily translate into a spike in the coyote population, though this is what many people assume. Again, increased sightings could be due to their current family dynamics which may cause individuals to wander farther afield.

Unusual weather conditions can have an effect on sightings. San Francisco has just been through a four-year drought. Drought conditions cause coyotes to hunt further afield and for longer hours. They become more visible to humans and more prone to incidents during these times when their activity overlaps with ours. It takes 8 full months for an ecosystem to recover from a drought.

Human changes to the environment, including new construction, will affect coyotes in an area. In San Francisco, coyotes may be lingering longer in neighborhoods recently, and therefore be seen more, because of the current program of thinning and eliminating dense and protective thickets in the parks, reducing coyotes’ normal secure habitat. Stopping the destruction of the habitat, and compensating for the exceptional weather or drought in various ways until the ecosystem has recovered, both are steps that could be taken to reduce sightings, and possible dog/coyote encounters, and coyotes’ spending the past-twilight hours in neighborhoods.

FEEDING

feeding coyotes is not good

Please don’t feed the coyotes. Feeding breaks down the barrier that keeps coyotes wild. If they become food conditioned — which is different from “habituation” (see below) — problems could develop, including approaching people, which increases the chances for a negative incident to occur. Feeding them also encourages them to hang around yards where people don’t want them.

Coyotes are opportunistic eaters, which means they can eat almost anything, but their preference in San Francisco is for gophers, squirrels and voles, which they eat whole: they need the meat, muscle, bones, fur — all of it — to nourish themselves properly. They also eat fruit, nuts, bugs, weak or juvenile raccoons, skunks, opossums, and possibly snakes. They prefer their whole foods over human-made foods, but if that human food is available, they’ll try it. And they will eat the occasional cat or small dog if circumstances are right — they don’t know who is a pet and who isn’t. Don’t create the right circumstances that could add your pet to the food chain. Please protect your pets by not allowing them to roam free and by supervising them closely when out-of-doors.

As top predators to an area, coyotes have helped rebalance the environment: they control rodents and some mesopredators, such as opossums, skunks and raccoons.

HABITUATION

a habituated coyote is not a dangerous coyote

Urban coyotes do not “fear” humans — that is an incorrect term. Rather they are “wary” of humans. This means that, although a coyote won’t flee lickety-split in fear when they see a human, they nonetheless will maintain distance and not approach us. And we, in turn, need to respect them and their wildness by keeping as far away from them as we can. “Habituation” is a normal progression in urban areas — you cannot prevent it because you cannot stop coyotes from seeing humans on a daily basis — they get used to seeing us. A habituated coyote is not a dangerous animal. In fact, the term “habituation” was first used to describe bears as being more dangerous if they got used to people and lost fear of us. This assumption has been turned on its head: scientists now know that bears who are habituated tend to ignore humans, whereas bears who have never seen humans become reactive. In Africa, to make gorillas less reactive to humans, for the tourist trade, people purposefully habituate them — they become less dangerous.

Coyotes also habituate to “hazing” tactics, which is why such tactics should not be used if a coyote is way out in left field. Scaring off a coyote should be used sparingly. It should be reserved for when a coyote has come too close to you. It is a useless tactic unless the coyote is closer than 50 or so feet to you, which generally delineates its critical distance for discomfort.

Note that “habituation” is different from “food conditioning”. When visibly feeding or hand-feeding a coyote, you are conditioning it to approach humans. Don’t feed coyotes.

THE ISSUE IS WITH PETS

Whereas coyotes don’t approach humans, dogs are a different story because of territorial issues and because of prey issues. In many ways, coyotes and dogs look alike, but coyotes and dogs are naturally antagonistic towards each other. Remember that coyotes keep other coyotes out of their territories. Coyotes are also both curious and suspicious of dogs: they may feel compelled to come in closer to investigate. Always supervise your pets to prevent incidents: the minute you see a coyote, leash and go in the other direction. Most dogs have a tendency to go chasing after coyotes. Please don’t allow your dog to do this.

coyote messaging a dog — the dog should have been kept away from the coyote

Coyotes have approached dogs. If they get too close, they could either grab a small dog or “message” a larger dog who the coyote considers a threat to its territory or its personal space. They can only do this when they get close enough. Don’t let them. You can prevent an incident by keeping your dog away from coyotes in the first place, by leashing when you see one, and by walking away from it. It’s no different than when you encounter a skunk with its tail up: keep your dog off of it, and move away from it.

Coyotes may follow dogs to find out what the dog is doing and where it is going (they do the same to non-family coyotes). If you and your dog are moving away from the coyote, and away from any denning site, the coyote soon will no longer follow. If you don’t want the coyote to follow at all, toss a small stone in its direction (not at it), and/or approach it (but don’t get too close) using your own blatantly angry body language and angry yelling. Noise alone, or waving flailing arms, is not always effective in making a coyote move — something has to move towards the coyote. And it isn’t going to help if you are too far away. You’ve got to get within the coyote’s critical distance — at most 50 feet — and you have to be assertive about it. Walking towards the coyote while slapping a newspaper viciously on your thigh works, but tossing stones towards it is probably more effective. However — and this is a very important “however” — if the coyote doesn’t budge, it is probably protecting a nearby den site. In this case, turn around and leave. Do not provoke an incident. See the above link in Bay Nature.

It’s always best to be proactive in keeping a coyote away. The minute you see a coyote, leash up and move away from it, and know how to shoo it off effectively if it comes closer to you than 50 feet.

Note that practically all scratches or bites by coyotes to humans are due to feeding the coyote, or to an owner getting him/herself between a coyote and a pet, so don’t do these things. And, never run from a coyote: this activity actually initiates the chase response in a coyote who may also nip at your heels. They also sometimes nip at car tires when the car is in motion. The phenomena is called “motion reactivity”.

ENCOUNTERS CAN BE SCARY

Encounters CAN be scary if you are unprepared and don’t know what to expect or what to do. Please learn what coyotes are like, not what you think they “should” be like — for instance, that they don’t “fear” humans but are “wary” of them, and not that “coyotes should be heard and not seen”. By knowing their true normal behaviors, and by knowing what to do *IF* they approach your dog, you will be informed and you will not be so fearful. For starters, watch the video, Coyotes As Neighbors: https://youtu.be/euG7R11aXq0, which will spell out normal coyote behavior and what you can do to keep coyotes away from a pet.

MANAGING COYOTES

The number one method of managing coyotes for coexistence is through human education and human behavior modification: that is what this posting is trying to help with. These have been shown to be extremely effective. The City of San Francisco has been lax in putting out signs or getting educational material to folks. Some of us have been filling the void, getting material, information and guidelines out to people, but as individuals or as small organizations, we have not been able to reach everyone. Please visit coyotecoexistence.com for specific information, and coyoteyipps.com.

Many cities have coexistence policies — they all work when folks abide by the guidelines. BUT, as with car driving laws, even if you know them and follow them, there will be some fender-benders that might be frightening. We have fewer than 100 coyotes in the City; the number of dogs is in the 250,000s. There is bound to be an incident now and then.

The number of real coyote incidents in the City is not many. There have been less than a handful of dog fatalities by coyotes — all were unleashed small dogs in known coyote areas — all were preventable. There have been many incidents of people being frightened and reporting “attacks” on their dogs. Few if any of these attacks were reported on a questionnaire which would tease out what actually occurred. Instead, these incidents have been spelled out on the social media with warnings of doom that is awaiting us all.

Most of the sightings of coyotes have been reported as charming. But there have been some fearful encounters, and recently groups of dog owners in some of the parks have turned decidedly against them. Social media tends to perpetuate, spread and amplify the fears, and encounters are inevitably worded as deliberate “aggressive attacks”. For instance, recently, there was a report of an attempted “attack” on a dog at 5:30 in the morning. However, a lone coyote, who weighs 35 pounds, is not going to “attack” a 130 pound Mastiff… Coyotes may watch dogs, follow, or hurry in your direction for many reasons, including curiosity, or investigation. They may jump up and down because of anxiety. These are not “attacks”, nor are they “attempted attacks”. Hopefully, by learning about coyotes, we can diminish the very real feeling of fear which comes from not knowing what is going on.

a coyote standing on a pathway, watching

Our Animal Care and Control Department has had many people report “aggressive” coyotes: but when questioned further, the majority of these reports were of a coyote just standing, or doing nothing but looking at the purported victim.

Two years ago I watched a man, straight faced, tell me that he had been frightened “out-of-his-wits” by a monster 100-pound coyote just a few moments before seeing me. He was visibly shaken. He hadn’t seen me watching the whole incident a little way down the path. The incident involved his dog chasing a coyote. The coyote turned around to face the dog. When the dog ran back to its owner, the coyote proceeded on to where it had been going. But the owner was left frightened, and justified his fright by saying it was a “monster 100-pound coyote”. If the dog had been leashed, the incident would not have happened. It happened in a park where everyone knows there are coyotes.

Parent coyotes are especially edgy at this time of year — it’s pupping season.

As this mother coyote foraged behind some low bushes, dog owners with their mostly leashed dogs walked by on a path about 100 feet away: they stopped and looked at her, though it might have been better if they had just walked on. None of the dogs approached her, though they might have communicated some kind of negativity through their facial expressions and body language. The coyote apparently didn’t like them looking at her, or she didn’t like their negative communication. OR, the dogs may simply have been too close for comfort. I was concentrating on her, so I couldn’t see what the issue was.

Note that she begins her complaining with little grunts and heaves: it’s an emotional and distressed reaction. As she initially grunts and heaves, she hasn’t decided to go all out with her barking. But soon, she lets loose. All the dog walkers “got it” once I explained to them what was going on: that this was an edgy mother and coyotes don’t like dogs around them. The walkers and their dogs moved on, and she soon quit her howling and then retreated into the bushes.

Her own mother, too, engaged in this exact same type of barking: it is a distressful bark and only occurs when these coyotes feel harassed or intruded upon by dogs. This type of barking is both a complaining — letting everyone know how she feels — and a communication of standing up for herself, though you can be sure that if a dog went after her, she would skedaddle quickly. The barking session shown here lasted only about three minutes, but I’ve listened to one that lasted well over 20 minutes.
